v0.7.0

The agent-agnostic epic — rauf's loop runner is no longer Claude-only. A pluggable
provider layer (packages/loop/src/providers/) lets the loop drive any CLI coding
agent via presets + a generic adapter, with agent selection, availability
pre-checks, and a hardened process-group lifecycle. Additive minor bump.

Added

• LLM-agnostic provider architecture in packages/loop — providers/
  (registry, presets, generic-CLI + CLI-agent adapters, shared types), an
  agent-selection resolver, and a process-group lifecycle for clean
  child-process teardown. The runner resolves and launches the configured agent
  by precedence and classifies its outcome provider-agnostically.
• .gitattributes — LF normalization (* text=auto eol=lf) + export-ignore
  for dev-only trees (specs/, tests/, .github/, test-sandbox/).
• npm-publishability prep on the packages the installer's rauf@0.6.0 pin
  targets (publishConfig / files / bin) — machinery only; no publish is
  executed (the npx rauf@0.6.0 path is documented as "available once rauf 0.6.0
  is published").
• Optional npm-publish.yml — workflow_dispatch-only publish machinery,
  outside the PR gate (not run by this feature).

Changed

• README — added a labeled cross-agent section linking feature-forge's
  cross-agent install story (loop-runner framing retained).
